Definitions

  • the present invention relates to a latching mechanism, in particular for an ejection device, with a housing on which a guide track for a driver is formed, wherein the driver along the guide track between two end positions is movable and the driver is biased by a spring in an end position.
  • DE 202009 000 038 discloses a detent mechanism for a pullout guide, in which an activator is fixed to a running rail, which engages in a receptacle on a driver.
  • the driver is slidably mounted between two end positions.
  • the driver is connected via a coupling element with a second driver which is movable along a control cam.
  • the second driver can also lock the first driver in a predetermined position.
  • This locking mechanism has been proven, however, has the disadvantage that many components are required for locking a movable furniture part.
  • a cam guide for a switching element is formed on the movable relative to the housing driver, wherein the cam guide has a detent recess on a loop-shaped portion on which the switching element can be latched against the force of the spring.
  • the switching element is movably mounted on the housing.
  • the switching element may be guided along a switching path formed on the housing, the switching path being linear or arcuate. is formed, so that an alternating movement of the switching element relative to the housing is possible.
  • an unlocking of the driver may be formed on the cam guide on the opposite side to the detent recess a starting slope, so that when a movement of the driver relative to the housing, the switching element is moved out of the detent recess.
  • Such manual unlocking can be done for example by pushing a drawer.
  • an ejection element for unlocking the switching element may be provided from the detent recess, which is operable by the user.
  • the spring is designed as a tension spring, which is fixed with one end to the housing and at the opposite end to the driver.
  • the spring can then on the one hand bias the latching mechanism, so that latching takes place against the force of the spring, and on the other hand, after unlocking of the switching element from the latching action a movement of the driver can be effected relative to the housing, which then, for example, an ejection of a movable furniture part, such as a door or a drawer, can effect.
  • the driver may be plate-shaped and be slidably mounted on at least one housing part.
  • the driver is held between two plate-shaped housing parts, so that a particularly flat design is made possible, in particular, the locking mechanism can then be mounted under a drawer.
  • the driver has a receptacle into which a projection or activator of a component which can be coupled to the driver can be inserted.
  • the projection may be arranged stationary, for example on a furniture body or a stationary rail of a pull-out, so that the driver is held stationary on the projection.
  • the housing is then moved relative to the driver, whereby the latching mechanism can be unlocked.
  • an ejection device is provided with a latching mechanism.
  • the ejection device can be attached to a movable Ren furniture part, such as a drawer or a sliding door, be mounted, for which purpose preferably the housing is fixed to the movable furniture part.
  • a couplable with the driver projection is set.
  • the ejection device preferably serves as an opening aid for a drawer, but can also be used for sliding doors, hinges or other movable parts.
  • Figure 1 is a perspective view of an inventive
  • Figure 2 is a perspective view of a pullout guide to
  • FIG. 3 is a perspective view of the pullout guide with the latching mechanism;
  • FIGS. 4A and 4B show two views of the latching mechanism in the latching position;
  • Figures 5A and 5B show two views of the locking mechanism when unlocking
  • Figs. 6A and 6B are two views of the detent mechanism after the ejecting operation
  • Figure 7 is a view of a modified latching mechanism
  • Figure 8 is a view of the latching mechanism of Figure 7 after unlocking the driver.
  • a latching mechanism 1 is mounted on a movable furniture part, such as a drawer 2, wherein the latching mechanism 1 has a housing 3, which is arranged adjacent to a front panel 4.
  • a driver 5 is movably mounted, wherein the driver 5 has a rear pin 6 and a front pin 7, which are held in a slot-shaped guide track.
  • the guideway comprises a linear portion 8, which is aligned parallel to the direction of movement of the drawer 2, and a Angled end portion 9, which is arranged obliquely or bent to the linear portion 8.
  • the driver 5 is biased by a spring 10 relative to the housing 3, wherein the spring 10 is held on a cantilever 11 of the housing 3 with one end and with the opposite end to a boom 12 of the driver 5.
  • a U-shaped receptacle 13 is further formed, in which a projection 14 engages, which is fixed to a guide rail 15.
  • the guide rail 15 is fixed to a side wall of a furniture body 16.
  • the pullout guide in addition to the guide rail 15 also includes a movable running rail 17 to which the drawer 2 is fixed.
  • the drawer 2 is movably mounted together with the housing 3 relative to the stationary projection 14.
  • the switching path 22 may be formed as a groove or recess on the housing 3.
  • the housing 3 is formed by two plates, between which the plate-shaped driver 5 is held.
  • the latching mechanism is in the locked position.
  • a cam guide 20 is formed, which is shown in Figure 4B with dashed lines, since the cam guide 20 is disposed concealed by an upper housing part.
  • the switching element 21 is movably mounted, which is additionally movable in the switching path 22.
  • the cam guide 20 includes a detent recess 23, on which the switching element 21 can be latched against the force of the spring 10.
  • the locking guide 23 is formed on a loop-shaped portion 25 of the cam guide 20, wherein opposite the locking recess 23, a run-on slope 24 is arranged so that upon movement of the housing 3 relative to the driver 5, the switching element 21 is unlocked.
  • the front panel 4 of the drawer 2 is pressed in the closing direction in the furniture body 16, so that the housing 3 is slightly moved in the closing direction, the projection 14 in the receptacle 13 remains coupled.
  • the switching element 21 is pressed over the wall of the switching path 22 against the run-on slope 24, whereby the switching element 21 is moved along the switching path 22.
  • the switching element 21 reaches a region laterally offset from the detent recess 23 and can now be moved along the loop-shaped portion 25 of the cam guide 20.
  • the housing 3 connected to the drawer 2 can be ejected in the opening direction, since the spring 10 can move the housing 3 relative to the driver 5.
  • the switching element 21 moves along the cam guide 20 as far as an outlet section 26 of the cam guide 20 (FIGS. 6A and 6B).
  • the driver 5 is thereby moved along the guideways 8 and 9 until the rear pin 6 passes into the angled end portion 9.
  • the driver 5 is pivoted away from the projection 14, so that the receptacle 13 comes out of engagement with the projection 14.
  • the housing 3 can be moved independently of the projection 14 in the opening direction.
  • FIG. 7 shows a modified embodiment of the latching mechanism 1.
  • the driver 5 is pivotally mounted on the housing 3, wherein the rear pin 6 is coupled via a spring 30 to the driver 5.
  • the front pin 7 of the driver 5 is fixed. If the user wants to unlock the drawer from the locked position shown in Figure 7, he can on the one hand push the drawer, so that an opening operation takes place, as was explained with respect to Figures 4 to 6. But it is also possible to open the drawer by a pulling movement. Then, due to the pivotal mounting of the driver 5 when pulling the drawer of the locking mechanism with the switching element 21 in the cam guide 20 is not unlocked, but the carrier 5 is pivoted so that the receptacle 13 out of engagement with the projection 14 passes (Figure 8). Then the user can open the drawer by a pulling movement, without damaging the locking mechanism. In a Schi manterrorism the projection 14 is pressed back into the receptacle 13 and the driver 5 is fixed against the force of the switching spring 30.
  • the housing 3 is formed of two plate-shaped housing parts, between which the plate-shaped carrier 5 is held. It is of course possible to modify the shape of the housing 3 and the driver 5 in a wide range. It is also conceivable strip-shaped embodiments of housing and driver or others
